【问题描述】：

我试图在 heroku 上部署我的 discord.js 机器人，但我总是收到错误并且机器人崩溃。我的代码很好，我在我的电脑上运行它，它没有给出任何错误。我按照此链接设置了我的 heroku 应用程序https://devcenter.heroku.com/articles/getting-started-with-nodejs#set-up。我完全按照它说的做了，但我收到了这个错误：

【问题讨论】：

这能回答你的问题吗？ Discord bot on Heroku throws an error: agent ??= new https.Agent

【参考方案1】：

Heroku 的 nodejs 版本非常低，遗憾的是您无法更新它，因此没有真正的方法可以修复它。如果它适用于 djs v12.5.3，你仍然可以在这里运行一个机器人

【讨论】：

哦.. 很快会有更新吗？

我不知道，对不起。我不是网站工作人员

【参考方案2】：

您可以在使用 heroku 时使用 engines 属性在 package.json 中指定节点版本。您可以尝试将版本设置为15 或更高版本吗？

  "name": "myapp",
  "description": "a really cool app",
  "version": "1.0.0",
  "engines": 
    "node": "15.x"
